Such SNMP information may include, for example, CPU utilization or server temperature.

The inline network performance monitoring module 70 of the device 14 is operable to provide the device 14 with inline network performance monitoring functionality. For example, according to various embodiments, the inline network performance monitoring module 70 allows the device 14 to inspect each packet that transits the device 14 and record certain information such as source/destination IP address, protocol, and source/destination ports.

According to various embodiments, the inline network performance monitoring module 70 also allows the device 14 to monitor all network traffic that passes between the device 14 and another device 14. Each device 14 has its time synchronized precisely to network time protocol servers (not shown). This allows for each device 14 to reference packet information with a common time reference. According to various embodiments, the inline network performance monitoring module 70 can record the exact time every packet leaves a device 14, and record items such as, for example, source/destination IP address, protocol, sequence number and source/destination port. As the packets travel across the Internet 16, the packets eventually reach the destination device 14. The inline network performance monitoring module 70 of the destination device 14 records the exact time the packet is received by the destination device 14 and items such as, for example, source/destination IP address, protocol, sequence number and source/destination port.

The logger module 72 of the device 14 is operable to provide the device 14 with logging functionality.

According to various embodiments, the data collected by the inline network management monitoring module 70 of each device 14 is forwarded to the logger module 72 of the associated device 14. After receiving the data, the logger modules 72 wait a random amount of time (e.g., between approximately 120 and 240 seconds) before transmitting the data to the management center 12. This random delay is to prevent all the devices 14 from sending their data back to the management center 12 at the same time. If the management center 12 cannot be reached, the device 14 may queue the data locally until the management center 12 can be reached. When the management center 12 is reached, the logger module 72 will transmit all of the queued data. The data that is transmitted uses a system queue which insures that regular user network traffic will always have priority and this data transfer will only use the unused bandwidth on the network connection.

The remote access server module 74 of the device 14 is operable to provide the device 14 with remote access capability. For example, according to various embodiments, the remote access server module 74 allows for the cooperation of the device 14 with a remote access client.

The IP and network interface module 76 is also operable to provide the device 14 with the capability to configure IP routing.

The QOS module 78 of the device 14 is operable to provide the device 14 with QOS functionality. For example, according to various embodiments, the QOS module 78 allows the device 14 to selectively transmit packets based on the relative importance of the packet. The QOS module 48 may also allow the device 14 to inspect each packet and determine a particular queue to send the packet to based on defined rules. Rules may be defined, for example, based on source/destination IP address and/or port information. If a packet does not match any rule, it may be sent to a default queue.

The VLAN module 80 of the device 14 is operable to provide the device 14 with VLAN functionality. For example, according to various embodiments, the first and third fast Ethernet ports 24, 28 of the device 14 that are connected to the local area network 18 and the demilitarized zone 32 may be configured as 802.1q trunk ports. The VLAN module 80 allows the device 14 to connect to many different VLANS from an Ethernet switch that has enabled trunking.

According to various embodiments, the device 14 may also automatically transmit performance information to the management center 12. The performance information may include, for example, a CPU utilization value for the device 14, a memory utilization value for the device 14, and a network interface bandwidth utilization value for the device 14. The performance data may also include, for example, the information obtained by the distributed network management poller module 68 of the device 14.

FIG. 10 illustrates various embodiments of a method of managing a network. According to various embodiments, the method includes receiving an activation key automatically transmitted from a device connected to the network, automatically transmitting a configuration to the device, automatically maintaining the configuration of the device, and receiving log information from the device. The network may be, for example, a local area network, or a number of local area networks that rely on the Internet to communicate with one another. The device may be, for example, the device 14 described hereinabove. The method may be utilized to provide an automated managed service for a complex network environment.

The process starts at block 200, where the management center 12 receives an activation key automatically transmitted from a device 14 connected to the network. Prior to the start of the process at block 200, the configuration of the device 14 is provisioned by an entity such as, for example, an administrator or a managed service provider. The entity may initiate the provisioning of the device 14 by logging onto the web-based management portal 90 and entering a license key associated with the device 14. The license key may be generated by a managed service provider and may be issued with the purchase of the device 14. The license key may include information such as the product type of the device 14, the term length of the license associated with the device 14, and the seller of the license. A hash function may be used to embed the information in the key to obscure the data, and the data may be read by the network manager to verify the authenticity of the license key.

Once the license key is received by the web-based management portal 90, the configuration of the device 14 may be provisioned via the web-based management portal 90. Setting the configuration of the device 14 may include setting the IP address of the device 14, and setting the configurations for the firewall configuration, the intrusion prevention configuration, the anti-virus configuration, the content filtering configuration, the anti-spam configuration, the VPN configuration, the DHCP server configuration, the network management configuration, the network interface configuration, the VLAN configuration, the QOS configuration and any other device configurations. Each configuration provisioned for the device 14 may be stored in the database cluster 82. According to various embodiments, a default configuration may be selected for the device 14.

During the provisioning process, an activation key associated with the device 14 is generated and may be printed out or e-mailed for later use. The configuration of the device 14 and the generation of the activation key may be completed from any location by accessing the web-based management portal 90.

Once the provisioning process is completed, the device 14 may be installed at the customer location. After the device 14 is connected to the local area network 18, the device 14 automatically attempts to DHCP for a wide area network IP address. As most Internet service providers assign IP addresses using DHCP, in most cases the device 14 will automatically obtain its wide area network IP address. For Internet service providers who do not use DHCP, the wide area network IP address can be obtained using PPPOE. Alternatively, a wide area network IP address may be statically assigned to the device 14.

According to various embodiments, the device 14 is configured with the DNS names of a number of the hosted servers that comprise the activation server 84. Once the device 14 obtains a wide area network IP address, the device 14 automatically attempts to communicate with one of the hosted servers that comprise the activation server 84. When the communication is successful, the activation key is entered and the device 14 transmits the activation key to the activation server 84. The activation key may be entered by an installer of the device 14. The process associated with block 200 may be repeated for any number of devices 14.

From block 200, the process advances to block 210, where the activation server 84 automatically transmits the configuration provisioned at block 200 to the device 14. After the device 14 receives its configuration from the activation server 84, an installer of the device 14 may be prompted to reboot the device 14. Once the device 14 reboots, the device 14 automatically connects to its assigned manager server 88 and the installation of the device 14 is complete. The process associated with block 210 may be repeated for any number of devices 14

From block 210, the process advances to block 220, where the management center 12 automatically maintains the configuration of the device 14. According to various embodiments, a flag is set in the database servers of the database cluster 82 when a change to the configuration of the device 14 is entered via the web-based management portal 90. According to various embodiments, the auto-provisioning manager module 100 periodically polls the database cluster 82 looking for changes to the configurations of the devices 14 managed by the manager server 88. When the auto-provisioning manager module 100 detects a device configuration that needs to be changed, the appropriate module (e.g., firewall, intrusion prevention, anti-virus, etc.) will generate the new configuration for the particular service and make the necessary configuration changes to the device 14 that needs to be updated. The process associated with block 220 may be repeated for any number of devices 14.

From block 220, the process advances to block 230, where the logger manager 86 receives log information from the device 14. As explained previously, the log information received from each device 14 may be compressed and encrypted, and may represent information associated with, for example, a firewall system, an intrusion prevention system, an anti-virus system, a content filtering system, an anti-spam system, etc. residing at the particular device 14. Once the logger manager 86 receives the log information, the logger manager 86 correlates the log information and makes it available to other elements of the management center 12. The correlated information may be utilized to determine both the real time and historical performance of the network.

FIG. 13 illustrates various embodiments of a method of managing a network. According to various embodiments, the method includes receiving network traffic information from a device connected to the network, automatically correlating the information, and automatically determining network performance based on the information. The network may be, for example, a local area network, or a number of local area networks that rely on the Internet to communicate with one another. The device may be, for example, the device 14 described hereinabove. The method may be utilized to provide an automated managed service for a complex network environment.

The process starts at block 310, where network traffic information is received from a device 14 connected to the network. The network traffic information may represent information that travels from one device 14 to another device 14. According to various embodiments, the network traffic information is captured at the device 14 and may include, for example, source/destination IP address, protocol, sequence number and source/destination port. According to various embodiments, the network traffic information transmitted from the device 14 is received by the manager server 88. The process associated with block 310 maybe repeated for any number of devices 14.

From block 310, the process advances to block 320, where the information is correlated. According to various embodiments the information may be correlated with network traffic information transmitted from any number of devices 14. According to various embodiments, the correlation of the information is conducted by the manager server 88.

From block 320, the process advances to block 330, where the network performance is determined based on the information. According to various embodiments, the network performance determination is made by the manager server 88. For example, assume that ten VOIP packets leave a first device 14 destined for a second device 14. As explained previously, the first device 14 may record the exact time each VOIP packet leaves, and the source/destination IP Address, protocol, sequence number and source/destination port for each VOIP packet. The first device 14 may then send this information to the manager server 88. Further assume that these ten VOIP packets travel over the Internet 16, the third and eighth VOIP packets are lost, dropped by a router that is over-utilized. The second device 14 will only see eight VOIP packets arrive, not knowing that the third and eighth packets were lost. The second device 14 may then record the exact time each packet is received and the source/destination IP Address, protocol, sequence number, and source/destination port for each received packet. The second device 14 may then send this information to the manager server 88. The manager server 88 may then examine the information transmitted from the first and second devices 12, 14 and determine, based on the IP Address, protocol, sequence number, and source/destination port that the packets recorded by both the first and second devices 14 are part of the same packet stream. Armed with this information, the manager server 88 may then determine the exact latency and jitter of each packet, and the packet loss (20% in this example) on a real application data stream. The process associated with block 330 may be repeated for network traffic information received from any number of devices 14.
